The latest ReactOS Newsletter is out. "I've been assured by our release engineer that there are only 2 blocking issues left and that [0.3.1] will be released soon. That said, a kind user compiled the 0.3.1 branch and provided the isos for public trials here. I spoke with our project leader about future releases and he went on to say that future releases (0.3.x) will be made every month or 2."
